Subject:   5.2.1 can't allocate large ammounts of memory in the kernel
Message-ID:  <000001c42d88$bb664360$507f6444@henry>

I have a KLD that allocates approximately 300 megs (or more) in the =
kernel,
mostly in 8k chunks.  On 5.1 I was able to build a kernel with:

options		VM_KMEM_SIZE=3D(24*1024*1024)
options		VM_KMEM_SIZE_MAX=3D(768*1024*1024)
options		VM_KMEM_SIZE_SCALE=3D(1024*1024)

This allowed plenty of room for both the module and some other items =
that
needed large amounts of kernel memory.  On 5.2.1-RELEASE I get "kmem map =
too
small" panics after allocating only 90 megs.  Has something changed?
Perhaps there is something else I need to tweak?
